Add Wind Force
VOP node

Layers a wind force onto a simulation.

This operator implicitly binds and exports the targetv and airresist attributes. It then takes the provided windspeed and airresist and composites them onto the previous value. This allows one to layer multiple wind effects in a consistent fashion.

Takes two values for alpha based on the surface orientation relative
to the camera and blends between the two with a
rolloff as the bias control, effectively removing the silhouettes of the
geometry edges.
